While researching the qha, I wanted something easier for checking out circular polarization. I discovered that 70% of all commercial FM radio stations run circular polarization. Home receivers are usually horizontal while mobiles are vertical. After looking up the types of antennas they use, I came up with two designs. The first has as much gain as a QHA but is much easier to build. I recommend...

How to construct a helcal wound loop, 2 element helical loop. Most of the authors designs are much longer in wavelength, each loop of the 2 element designs actually have maximum performance at a percentage of wavelength approaching between 1/3rd & 1/2 wavelength each loop. Thus termed Fractional wave vs magnetic loop. Therefore the constant current usually referred to in a magnetic loop no...
